NI-2530B Switch Scan List

Question

I am having issues with the 2530B reading in my scan list. I have had no issues until now. In Test Stand I create a scan list, Example: "ch0->com0 & com0->pcom1 & ch16->pcom1;". When I intialize, configure, initiate, etc the switch acts correctly. When I send it a scan list, Example: "ch0->com0 & com0->pcom1 & ch16->pcom1; ~ch0->com0 && ch1->com0;" (With mode using Software Trigger) it does not read anything in the list and does not open/close any switches. I have used this switch for awhile now but some odd reason I am having issues with it right now and can not figure it out.
To go a little farther, I use GetRelayPosition to step through each relay to check after I initiated the scan. When I use the second example scan, I get a response back of NISWITCH_VAL_OPEN (10) for all relays, but when I use the first scan, the one that works correctly, I get no repsonse back from GetRelayPosition and the return value stays at '0'. Everything seems odd. I have been using the Switch for months now and created hundreds of scan lists of different types but not sure why I am having these problems now.

Answer 1

Correct about relay position while scanning, but once I abort I can check then also correct? If so, that is what I did and still got the '10' for the one not working correctly and '0' for the one that worked instead of '11'. I am using Test Stand and using niswitch32 dll to call the functions. I have my own dll I create the scan list in. And yes, when I include ';' output signal to wait for software triggers that is the scan lists not working correctly. IIf my scan list just contains one scan through, it works. Which is odd because I have been using this switch, funcitons, and my own scan lists for months and not sure why this is happening now. I can include some code but the only code would be creation of a scan list and I provided what it looks like above.
InitWithTopology ( "Name", "2530/Independent", False, True, handle);
ConfigureScanTrigger (handle, 0.0, software trigger (3), none (0));
Create My Scan List
ConfigureScanList (handle, list, none(0) );
InitiateScan(handle);
Measure from external dmm
When my scan lists look like:
com0->pcom1 & com2->pcom3 & ch16->pcom1 & ch32->com2 & ch1->com0 & ch49->pcom3;
The DMM takes the correct reading and everything works.
When my scan lists looks like (Or anything involving multiple triggers):
com0->pcom1 & com2->pcom3 & ch16->pcom1 & ch32->com2 & ch1->com0 & ch49->pcom3; ~ch1->com0 & ch0->com0; ~ch49->pcom3 & ch48->pcom3 &
It does not work and nothing responds. It does not stop at the first output signal ';' and wait for a trigger as I do not even get a reading like the first scan list.
